Applicationfiled June 17,1903- Serial No. 161,946. ill'o modali To allwhom it may concern:

Be it known that I,- LmvILLE V. Lone, a citizen of the United States,residing at Bowerston, in the county of Harrison and State of Ohio, haveinvented a new and useful .Hose- Coupling, of which the following isaspecifi catiom The invention relates to improvemfents'inhose-couplings.

The object of the present invention is to improve the construction ofhose-couplings and to provide asimple, inexpensive, vandeflicient one ofgreat strength and durability in which the parts will always-be inproper position to enable a hose to be readily coupled without turningor twisting the lengths thereof.

'A further object of theinvention is to provide a hose-coupling whichwill enable hose to be rapidly coupled and uncoupled and which willpermit the same to be dragged over streets, curbing, fences, andotherobstruc-.

tions without liability of becoming accidentally uncoupled It is alsothe object of the invention to provide a hose-coupling adap to exert adirect pull on its sections, to preve tany binding or frictional contactof the sections on each other,

and the consequent resistance \to such move.- ment, and capable ofenablingaSteam, water, and air tight joint to be readily made. Withthese and other objects inview the invention consists in theconstruction and novel combination and arrangement of parts hereinalfterfully described, illustrated in the accompanying drawings, and pointedout in the itbeing understood that various changes in the form,proportion, size,: and minor details of construction within the scope ofthe claims may be" resorted to with-' out departing from the spirit orsacrificing any of the advantages of the invention In the drawings,Figure 1 is a side elevation of a hose coupling constructed inaccordance with this invention, the parts being shown locked in fulllines and unlocked in dotted lines. Fig. 2 is a longitudinal sectionalView.

Fig. 3 isa transverse sectional view on the line 3 3 of Fig. 2. Fig. 4is adetail ,perspectiveview of the locking mechanism.

Like numerals of reference designate corresponding parts in all thefigures of thedraw- 1 and 2 designate sections preferably constructed ofcast malleable iron or other suitable metal and provided with outerportions 3'and 4 adapted 'to receive hose in theordinary manner, andthese outer portions may be smooth, as shown in theaccompanyingdrawings, or they-may be corrugated or provided with dull threads toprevent the hose from slipping. Any means may be employed for securingthe hose to theouter portions 3 and def the sections. j

' The section 1 is provided with a smooth inner portion 5, which isadapted to fit into the adjacent inner portion 6v of thesection 2,'andthe'latter is enlarged, as shown, to receive the shoulder 7. Theexterior annular shoulder 7 is inwardly beveled'or undercut, as clearlya curved yoke 8, which conforms to the con-' section-'1 and toprovide'an exterior annular shown in Fig. 2, to receive andinterlock-with figuration of the section 2 and which is beveled at itsinner engaging edge 9 to fit the ,beveled or undercut portion of thesection 2. "The yoke is rigidly secured toa pair .of side bars 10, whichare pivoted to the sides 11 ofa forked or bifurcated operating-lever 12.The

sides of the forked or bifurcated operating.-

-lever 12 are adapted to straddle the section 1 of the coupling, andtheyare piv'oted'near their outer ends by rivets 13 or other suitablefastening devices to a collarl ig The sides 11' of the forked orbifurcated lever form short outer arms 15, which are-pivoted totheadjacent ends of the side bars 10 by rivets-16 or other suitablefastening devices.

"Thecollar 14 which is, arranged tion 1 of the coupling, -i s adapted torotate freely thereon to enable any adj ustment of the on the sec--looking mechanismto be effected Withoutturn: ing'or twisting the hose.The collar is ar-,

ranged contiguous to an annular enlargement- 17 locatedbetwee'n the endsof the section 1 and provided with an annular groove 18, re-' ceivingthe engaging portions of-a pair of L- "shaped arms 19. The L-shaped arms19, which are located. at diametrically opposite points,

are secured by screws 20 orother suitable fastening devices tothecollar, and they ex tend over the adjacent portion of the annularenlargement and project into the annular groove thereof. collar isswiveled onthe section 1 and is adapted to rotate freely. Instead ofswiveling the collar to the section 1 by means of the L- shaped armssuitable stops, such as set-screws or the like, may be mounted on thesection 1 at the outer side of the collar to confine the same in'itspositioncontiguous to the annular enlargement.

The lever when viewed in side elevation is approximatelysigmoidlycurved, as illustrated in Fig.2 of the drawings, to enable theouterportion to lie close to the coupling when the parts are locked andto present a smooth exterior to enable a hose to be dragged along astreet, over curbs, and rough places without liability of accidentallyunlocking the sections.

.The coupling will permit a hose to be dragged over fences and to behandled similar to an ordinary hose with threaded couplings withoutliability of becoming accidentally unfastened. The outer portion of thelever forms a grip or handle, and the curve thereof may be increased, ifdesired, sufficiently to enable the fingers of the operator to heintroduced between the handle and the coupling.

The lever and the yoke are adapted to exert a direct longitudinal pullon the sections which are drawn together, a rubber gasket or washer 2lbeing interposed between the intermediate annular enlargement 17 and theend of the section 20f the coupling. One or more rings or washers may beemployed, and these may be of any desired size to secure the desiredjoint.

The sections are readily uncoupled by simply swinging the operatinglever from the position illustrated in full lines in Fig. 1 to thatshown invdotted lines, and in coupling the sections the yoke is firstarranged in the groove 22 between the shoulder 7 and an enlargement 23,and theleveris then swung forward or inward against the coupling to theposition shown in full lines in Fig.1.;-

' What I claim is 1. A coupling comprising two sections, one

:of the sections being provided with an annula'r shoulder, and the otherhaving an annular By this construction the,

enlargement, a collar arranged on the section having -the enlargementand capable of rotation, said collar being provided with means forinterlocking it with the said enlargement, a lever carried by thecollar, and a yoke connected with the lever and engaging the shoulder,substantially as. described.

2. A coupling comprising two sections, one of the sections beingprovided with a shoulder and the other section having an annularenlargement, a collar arranged on the latter section and provided witharms interlocked with the said enlargement, a lever fulcrumed on thecollar, and a yoke connected with the lever and engaging the shoulder,substantially as described.

3. A coupling comprising a section provided with an intermediate annularenlargement hav ing an annular groove, a collar fittedon the saidsection at the outer side of the enlarge" mentand provided with Lshapedarms engaging the groove, a leverfulcrumed on the collar, a yokeconnected with the lever, and a section having a shoulder for engaging,the yoke, substantially as described.

4. A coupling comprising the section 1 having an exterior annularenlargement provided with an annular groove, the section 2 enlarged toreceive the section 1 and to form a shoulder,-

a collar arranged on the section 1 and provided with means for engagingthe said groove, a lever fulcrumed on the collar, a yoke connected withthe lever and engaging the said shoulder, .and a packing-ring or washerinterposed between the section2and the enlargement of the section 1,substantially as described.

5. A-coupling comprising two sections, one ofswhich is provided with ashoulder and the other having an annular enlargement,a rotatable collararranged on the latter section and provided with arms interlocked withthe said enlargement, a yokeengaging the shoulder on the other'section,and. means connecting the yoke to the collar, substantially asdescribed.

In testimony that I claim the foregoing as my own I have hereto afiixedmy signature in the presence of two witnesses.
